ixgbe: fix ring assignment issues for SR-IOV and drop cases
This change fixes the fact that we would trigger a null pointer dereference or specify the wrong ring if the rings were restored. This change makes certain that the DROP queue is a static value, and all other rings are based on the ring offsets for the PF.
